Connecting faces that are out of alignment
If I'm understanding your question:

Select the ear loop and detach it from the rest of the mesh pressing L;
Activate the proportional editing with O;
Select the end-face of the loop (the one you want to bring to the mask mesh);
Move it with G and setting the action radius with the mouse wheel (be careful not to reach the other end with a big radius, or you'll move it too).
